Ok so I remember, prior to updating to Lion (don't know if this has anything to do with my problem) within' iMovie '11 there was a feature that, when you drag one clip on top of another clip, you'd get a pop-up menu that would give you some options of what to do with said clip, such as green screen, picture in picture, overlay ect. Now, however, I get much fewer options. I now only get Insert or Replace, which doesn't give me the effect I want (PIP). Has this feature been removed from iMovie '11 recently? Here's a pic of what I mean. That list previously had MANY more options. NEVERMIND! I figured it out.
